We Built Our Reputation on Reliability

Out on the water, the only thing that matters is reliability. Because everybody knows the money stops as soon as your generator does. That’s where we come in. We’re KOHLER® Marine. And for nearly 100 years, we've built some of the best commercial generators on water. Truth is, we're a lot like you. We're good at what we do. And we make no apologies for it. Every weld, wire and circuit is a badge of honor. If our craftsmen have touched it, it is good and true. And if our name is on it, it’s going to work.

The Decision-Maker® 3500
Our exclusive paralleling controller features an easy-to-use digital display. And it’s multilingual, displaying text in English, Spanish, Arabic, Chinese or Portuguese.

Proven Reliability
We are a company of craftsmen guided by a singular purpose: quality. Every KOHLER commercial marine generator is extensively quality tested start to finish – before model release and before leaving the factory. The result is proven reliability.

No-hassle Warranty
We cover the first year, with the option to extend to three years.

Easy to Use, Easy on Your Budget
We created the world’s first commercial marine generators with factory-installed,pre-tested paralleling controllers and automatic voltage regulators.* Everything is automatic and easier to use than ever before.

Instant Auto Transfer/Paralleling
All Decision-Maker 3500 controllers are equipped with auto transfer functionality. When the first generator’s load is light, the second generator automatically drops off. When the load is heavy, the second generator automatically comes online to provide the power needed to carry the load. Or if one generator is in trouble, the second generator senses the problem, starts up and takes the load automatically.

The Decision-Maker 3500 is compatible with existing systems, so repowers are easier than ever. When wired for V-bias/S-bias inputs or droop, it can parallel with existing load-share modules for even more installation options.

Remote Monitoring
Monitor and control your generators from your boat’s existing monitoring system. Or enjoy a more comprehensive experience with generator- specificmonitors from Kohler.

Proper Engine Combustion
Our electronically controlled high-pressure common rail fuel system provides just the right amount of fuel at just the right time.

Corrosion & Vibration Protection
Fully potted circuit boards and sealed connectors protect the controller and alternator from marine environment conditions and heavy vibration

Nearly every component is designed, built and serviced by Kohler. Just the way it should be.
